R factor = 0.049; wR factor = 0.143; data-to-parameter ratio = 24.2. The title compound, C17H26BrNO, exhibits a small twist between the amide residue and the benzene ring [C—N—C— C torsion angle = 29.4 (5)]. In the crystal, the amido NH group is involved in N—H O hydrogen bonding, which connects molecules into chains parallel to the c axis.
